Update 3.0 to 3.1
Version 3.1:
I have made several changes to the code that renders wire frame
drawings and displays some data, like the projection parameters
(azimuth and elevation of the structure and the radiation pattern) and
gain values. This has resulted in a faster and smoother animation of
these drawings and reduced workload on the processor during dragging
of these images.  I have also reduced the default minimum size of
xnec2c's windows, as I had reports that they would not fit in the
displays of some laptops or monitors, with resolutions on the lower
side.
